"For many deceivers have gone out into the world who do
not confess Jesus Christ as coming [erchomai] in the flesh.
This is a deceiver and an antichrist" (2 John 1:7).

The Greek verb erchomai means 'to come' with a notion of
movement. Here, it is conjugated at the present participle tense
as in Revelation 1:8, "The Lord, who is and who was and
who is to come (literally 'coming')" (Revelation
1:8), whereas in 1 John 4:2, it is conjugated at the past
participle tense, "Every spirit that confesses that Jesus
Christ has come (literally 'having come') in the
flesh is of God".

At the
Ascension of Jesus, two angels (men in white clothing) said to the
disciples, "This same Jesus, who was taken up from you
into heaven, will so come in like manner as you saw Him go into
heaven" (Acts 1:11). When Jesus returns for His Bride, He
will come in the same way He left this earth, that is to say on a
cloud, and with the same glorified body of flesh. Deceivers and
the Antichrist deny the fact that Jesus will return in the same
body of flesh in order to deprive us – since we're called to
be part of the Bride – of our reward (2 John 1:8).
